Apliicen'id December 14, 1892. lserai No. 455,118. (no man.)

T0 all whom it may concern:

Beit known that I, FREDERICK LMCGAHAN,

of Indianapolis, county of Marion, and State ofIndiana, have invented certain newand usel ful Improvements in Oil-Burners;l and I do hereby declare that the following is a full,`

My invention relates to new and useful improvements in an oil burner which is spe'- cially adapted for use `in grates and closed` fireplaces, and Whose effect will be equal to y natural gas, superiorto coal, and whose flame,`

will be clean and present an attractive appearance,this result being obtained through the construction and form of the burner, as will be hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of a lire place specially constructed for use with my improved burner. Fig. 2 is a front View of the casting in which the burner proper is placed and shows the flue leading from the burner chamber to the chimney, the front or facing of the fire place being removed. Fig. 3 is a vertical section of Fig. 2 on the line X-X, the front or facing being in place. Fig. 4 isan enlargedelevation of the burner proper and the lighting or drip pan in which it sits. Fig. 5 is a top view of the same, and Fig. 6 is 'a cross section through the same on the line Y--Y.v

In detail, l represents a tire place of the usual form, and 2 is a metal cast-ing or shell which is adapted to be set therein, this casting having a iue 3 extending entirely around it and surrounding the burner chamber 4, a

partition/5 closing the flue at the top, and an.

opening being formed on either side, one into the burner chamber and the other into the chimney above.

A deiector 6 is formed in the rear wall `of the chamber4 for throwing the iiame toward the front of the same before it enters the flue 3 and the entire fronts of the flue and the burner chamber are closed, a layer of asbestus paper 7 or other fire-proof material being first secured over the front of the flue, this being covered by tiling 8 when the front 9 of the burner chamber, which is preferably of metal, is set in place, it being secured to the main castingor shell2 by means of screws,

the front 9 holding firmly in place the firepro'of covering and'tiling over the flue` 3.

The front'9 hasclosable draft openings 10 near its bottom which may be regulated as desired, and a door ll above for lighting the fire, a larger sliding door 12 the width of the front 9 workin g above this/having mica lights, and has also chains or cords 13 attached. to its lower'end onthe inside, these- Working over slides or pulleys 14 with bearings in the walls of the casting2, weights 15 being secured to the other ends of the chains for balancing the door 12 and making it convenient and easy to open:

On the vrear wall of the main casting and near thebottom. ofthe burner chamber is formed or secured a pan 16, this being above a line of the draft openingsz10,and a burner 17, is supported ink this pan, as shown in detail in Figs. 4, 5 and v6, it having a sloping front and ends with two or more series of grooves formed therein, three being shown, and above each is a projecting rib 19 in the outer face of which is a slot 20, these opening into the oil chambers 21, there being one of these chambers for each slot, and the two lower ribs forming drip pans for the series of grooves 18 above them.

Connected with each of the oil chambers 2l is a pipe 22 which extends out through the shell 2 and comes'out into the room from behind the mantel, where they are all connected with an oil cylinder 23 which has a valve "24 seated therein for regulating the iow of oil through each of the pipes 22, the oil entering the cylinder from any suitable source through the pipe 26. There beingaseparate valve 24 for each pipe 22, the feed of oil to the burner 17 can be perfectly controlled and regulated as desired, and a glass gage 25 attached to the front of the cylinder 23 always indicates the proper supply of oil.

The operation of the burner is as follows: It being connected with a supplyY of oil, the lower valve is preferably opened and the oil flows out into the-lower oil chamber 21 in the burner and through the slot 20 intothe grooves 18 and pan 16, when it may be lighted, and as soon as the burner is heated, the other valves may be opened and the oil will iiow IOO from the other chambers 21 and the desired heat be obtained, the burner when perfectly heated having an effect to warm the oil before it escapes from the chambers 21, and thus aids in securing perfect combustion. The flame from the burner is thrown out toward the front of the burner chamber 4 by the deileetor 6, and then escapes into the flue 3, where it and the accompanying products of combustion are carried entirely around the chamber4 before they reach the chimney, and

l during which time the tiling 8 is heated and thus more heat is radiated into the room, securing the most favorable result with an economical use of oil. Through the draftopenings 10, the air draft may be regulated and the air admitted is heated by contact with the flue 3, and being thus lighter, when it mixes with the flame a perfect combustion is obtained, and no soot or carbon deposits are left in the burner chamber.

The construction of the burner is such as to operate successfully in any fire place, but the best results are obtained where it is set in a shell constructed as hereinbefore described.

The burner may be modified, if desired, to represent lire logs, and where this is done a separate series of grooves with an oil chamber would be-formed in each log, the grooves always being perfectly horizontal, but the method of feeding and the construction of the other parts would remain the same, giving a re that is equal to natural gas and superior to coal, the flame being the same over all parts of the burner.

IIa-ving fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. An oil burner having two or more chambers therein connected independently with an oil supply, two or more series of grooves formed in the sides of such burner and openings from such oil chambers to such grooves for feeding them with oil, substantially as set forth.

2. An oil burner having sloping sides with two or m01 e series of grooves formed therein, each series connected by a slot with a separate chamber within the burner through which they are supplied with oil, and a drip pan below each series of grooves, substantially as set forth.

3. In an oil burner, a casting having two or more chambers formed therein independently connected with an oil supply, two or more series of grooves formed in the sloping sides of such burner, projecting ribs above each series of grooves, the upper ones forming drip pans for the series above, slots in such ribs opening from the oil chambers, and a drip pan suitably supported in which the burner is adapted to rest, substantially as set forth.

4. An oil burner having sloping sides with two or more series of grooves formed therein, each series connected byan opening Withaseparate chamber within the burner, such chambers connected by pipes with an oil cylinder outside the fire-place having independent valves therein for regulating the oil supply to each pipe, substantially as shown and described.

In witness whereof I have hereuntoset my hand this 3d day of December, 1892.
